Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/wshobson/agents --skill unity-ecs-patterns- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads unity-ecs-patterns automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
Security audits
Independent scans of the skill's instructions and bundled files.
SKILL.md
The instructions your agent reads when the skill is triggered.
Unity ECS Patterns
Production patterns for Unity's Data-Oriented Technology Stack (DOTS) including Entity Component System, Job System, and Burst Compiler.
When to Use This Skill
- Building high-performance Unity games
- Managing thousands of entities efficiently
- Implementing data-oriented game systems
- Optimizing CPU-bound game logic
- Converting OOP game code to ECS
- Using Jobs and Burst for parallelization
Core Concepts
1. ECS vs OOP
| Aspect | Traditional OOP | ECS/DOTS |
|---|---|---|
| Data layout | Object-oriented | Data-oriented |
| Memory | Scattered | Contiguous |
| Processing | Per-object | Batched |
| Scaling | Poor with count | Linear scaling |
| Best for | Complex behaviors | Mass simulation |
2. DOTS Components
Entity: Lightweight ID (no data)
Component: Pure data (no behavior)
System: Logic that processes components
World: Container for entities
Archetype: Unique combination of components
Chunk: Memory block for same-archetype entities
Detailed patterns and worked examples
Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.
Best Practices
Do's
- Use ISystem over SystemBase - Better performance
- Burst compile everything - Massive speedup
- Batch structural changes - Use ECB
- Profile with Profiler - Identify bottlenecks
- Use Aspects - Clean component grouping
Don'ts
- Don't use managed types - Breaks Burst
- Don't structural change in jobs - Use ECB
- Don't over-architect - Start simple
- Don't ignore chunk utilization - Group similar entities
- Don't forget disposal - Native collections leak
